Abstract This study describes the one-step in situ hydrothermal construction of N/Ti3+ co-doping biphasic TiO2/Bi2WO6 heterojunctions (NT-TBWx) and investigates their sonophotocatalytic degradation of organic contaminants in water. The obtained samples are characterized in detail including X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Ultraviolet diffuse reflectance spectroscopy, etc. Their photocatalytic, sonocatalytic, and sonophotocatalytic performance are compared by the degradation of organic pollutants and found the degradation rate according to the order: photocatalysis
